Yes, my short google search yesterday gave me also something from 2003 -- someone reported that it is possible by setting label, show and realize it, and then calling 3 times gtk-parent-widget to get the tree view header widget and then set the color. I have not saved that search result, it is a hack which may work for a specific GTK version, but not generally. It is sad that it does not work for you, but generally it is not a good idea to change the default style that much. You may ask at IRC or StackOverflow, maybe there the change to be heard by GTK developers is better. Maybe also say why you think that you need it, so motivation to answer is better. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
